1. Parallel reluctance ( \mathcalR_p = \frac11/R_1 + 1/R_2 = \frac11\times 10^-6 + 0.5\times 10^-6 = 0.667 \times 10^6 )
2. Total reluctance ( \mathcalR_T = \mathcalR_c + \mathcalR_p = 0.5\times 10^6 + 0.667\times 10^6 = 1.167\times 10^6 )
3. Total flux ( \Phi_T = 1000 / 1.167\times 10^6 = 8.57\times 10^-4 , \textWb )
4. MMF across parallel section ( = \Phi_T \times \mathcalR_p = (8.57\times 10^-4)(0.667\times 10^6) = 571 , \textAt )
5. Branch fluxes: ( \Phi_1 = 571 / 1\times 10^6 = 5.71\times 10^-4 , \textWb ), ( \Phi_2 = 571 / 2\times 10^6 = 2.855\times 10^-4 , \textWb ) (Check: ( \Phi_1 + \Phi_2 = 8.565\times 10^-4 ), matches total)

A magnetic circuit consists of a coil of 200 turns, a core with a cross-sectional area of 0.02 m², and a length of 0.8 m. The air gap length is 0.5 mm. If the current through the coil is 8 A, find the magnetic flux. magnetic circuits problems and solutions pdf
